DIY E fuel and results

mercredi 3 septembre 2014

So this Labor Day weekend I finally found time ( 4 years later ) to do my E fuel set up.



I had previously been running napa fuel filter bases with a 10u water separator and a 2u filter on my frame rail on the suction side of the factory lift pump, using 5/16 hose, since the factory selector valve on the ford is a 5/16 line..



So I left the 5/16 suction from the selector, into the napa filter head, through the same 10u water/fuel separator, then into a 2001 F350 factory fuel pump. The pump uses 5/16 inlet/outlet, so I continued with a 5/16 line into a napa filter head with a 2u filter. Out of the napa filter head, I ran a 3/8 line towards the pump. I bypassed the factory lift pump with a BB Chevy block off plate.



I ran a 3/8 line into the engine bay to a fitting with 3/8 in and out with a 1/8 pipe on top. I put I pipe T there. Out of one 1/8 pipe, I ran a mechanical fuel gauge for under hood tuning and the other, my electric sender for in cab monitoring.



From there it a 6" 3/8 line into a T where is feeding a dual feed to the P pump.



On the return side it's the factory OFV (currently) with a bic spring feeding the factory return from the pump. Then I ran a 5/16 line to the injector return. I used an air dog fitting with 1/4 pipe on each end and the M6 fitting on top at the injector return. Used 5/16, 1/4 pipe fittings

On the return and a straight 5/16 line to the ford selector valve.



Currently running 50 psi idle, and for the first time smooth on my gauge. Been through 3 autometer senders with snubber and braided hose.



At 3/4 throttle it pulls down to 30 psi



Idle is way smoother and quieter, and the "tick tick tick" after I bick pen springed my OFV is all gone.



I pan to swap to a tork tek OFV still.. But over all, the 3/8 pressure feed and electric pump were a good upgrade.



The mid range power was a noticeable gain. And those of you who said to up my fuel pressure to get the dyno numbers I was after. I think this was a great step.



Cheers

Bob
